An adjustable magnet carrier (100) for a rotary valve indicator apparatus (10) is disclosed. The adjustable magnet carrier (100) includes an extension member (117) having extension member body (118), an extension member body top (119), and an extension body base (121). Upper and lower magnet carriers (144, 146) selectively rotate about extension member (117) to adjust the stand-off between the magnets (102, 104) and the magnetically responsive switches (30, 32). The magnetically responsive switches are hermetically sealed within separate electronic housing (15). Light-emitting diodes (42, 44) radiate from electronics switch housing (15) in response to switches (30, 32). Drive shafts (124, 128) rotate the magnet carriers (144, 146). The outer surfaces of the upper and lower magnet carriers (144, 146), the ends of drive shafts (124, 128), and the light-emitting diodes (42, 44) are color-coded to correspond to each other and to the open and closed positions of rotary valve element (19). |
